Answer:
[tex]x=\sqrt{2}[/tex], [tex]x=- \sqrt{2}[/tex]
Step-by-step explanation:
Given:
[tex]1.2x^2-2.4=0[/tex]
We need to find roots of the equation.
First we will solve the above equation and then will remove the root for the same.
[tex]1.2x^2-2.4=0\\1.2x^2=2.4\\x^2=\frac{2.4}{1.2}=2\\[/tex]
Now to find the roots we need to square root on both side.
[tex]\sqrt{x^2}=\sqrt{2}\\[/tex]
square and square root gets cancelled we get.
[tex]x= \sqrt{2}[/tex], [tex]x= - \sqrt{2}[/tex]
